We study the impact of preschool targeted at children from low-income families over the life cycle and across generations, and examine its interaction with an infant health intervention. Using Danish administrative data with variation in the timing of program implementation over the period 1933–1960, we find lasting benefits of access to preschool on adult educational attainment, earnings, and survival beyond age 65. We also show that children of women exposed to preschool obtain more education by age 25. However, exposure to a nurse home visiting program in infancy reduces the added value of preschool, implying that the programs serve as partial substitutes.

贫困儿童学前班的附加值是什么？长期和代际影响以及与婴儿健康干预的相互作用

我们研究了针对低收入家庭儿童在整个生命周期和跨代的学前教育的影响，并研究了它与婴儿健康干预措施的相互作用。使用丹麦行政数据以及 1933 年至 1960 年期间计划实施时间的变化，我们发现接受学前教育对成人教育程度、收入和 65 岁以上的生存有持久的好处。学前班在 25 岁之前获得更多的教育。然而，在婴儿期接触护士家访计划会降低学前班的附加值，这意味着该计划可作为部分替代品。
